Description

Coil component and program for manufacturing coil component

Specify the coil components and the procedure used to make the coil components. The coil component is in particular formed as an electrical component, for example as an inductive component. In particular, the coil component can act as a throttle or as a transformer.

In order to manufacture a coil component, it is necessary to deform the wire so that it winds, for example, around a coil form. Print publication WO 2011/015491 A1 describes a current-compensated throttle in which there is a manufacturing procedure in which a preformed coil is wound around a ferrite core. Print publication DE 3540098 A1 describes a (manufacturing) procedure for a toroidal core coil with wires.

It is an object of the invention to provide an improved coil assembly and an improved procedure for manufacturing a coil component.

According to a first aspect of the invention, a coil component refers to a coil having a coil configuration and at least one coil wound coil configuration. In particular, the coil configuration has a closed form, such as a closed frame. This closed form is better before the coil is selected Choose well. For example, the closed form can be a single piece. This means that the closed form, preferably a complete coil configuration, has no slot welds or the like. This means that the coil configuration does not require subsequent components.

The coil configuration may have a magnetic core to increase inductance, particularly a ferrite core, or may be formed as a magnetic core. In particular, the magnetic core has a closed form. This closed form is preferably selected before the coil is selected. The core is preferably formed in a single piece. This means that the core has no groove soldering or the like. Therefore, the core does not require subsequent components. For example, the coil configuration can have a housing surrounding the magnetic core. Alternatively, it may be provided without a shell so that the coil directly winds the core.

The coil consists of at least one wound wire wound around the coil configuration, in particular wound on a section of the coil configuration. The winding geometry causes the winding to rotate about the coil configuration, in particular around the corresponding coil configuration section. For example, at least in the manufacturing process, at least around the coil configuration, the winding is rotatable. The "rotatable" rotation of the winding referred to herein is possible without the need for entanglement deformation and damage to the coil configuration and winding. For this, the winding on the coil configuration must be sufficiently loose. In the case of a coil component that is prepared, for example, the winding can no longer be wrapped around the coil due to subsequent deformation of the housing or subsequent winding of the wire and/or the end of the wire. The configuration rotates.

For example, the winding is circular in plan view. Specifically, the wire is wound into a circular spiral around the configuration of the coil. Accordingly, the coil, which includes the winding of all the wires, may have a basic form of a cylindrical column. In this case, the end of the wire and/or the end of the wire can protrude (protrude) in this basic configuration.

In one embodiment, the coil configuration (especially comprising the winding section) has a circumferential line in a cross-sectional view that differs from the top view geometry of the wound form.

For example, in the cross-sectional view, the coil configuration has an outer circumferential line of the corner, and the wound top view has a circular shape. For example, the outer circumference of the coil configuration has at least one straight section. In particular, the outer circumference of the coil configuration may have a rectangular shape.

In an alternate embodiment, the coil configuration profile in cross-sectional view corresponds to a wound form in top view c. For example, both the perimeter line and the winding have a circular geometry.

In one embodiment, which corresponds to a wound coil axis, the coil has a longitudinal axis. In particular, the coil has a cylindrical column basic configuration. The coil is arranged around a section of the coil configuration, for example an arc. For example, the coil configuration is a ring shape. In one embodiment, the coil axis does not adjust the course of the coil configuration curve. For example, a cylindrical cylindrical coil is arranged on the toroidal coil configuration.

In one embodiment, there is at least one gap between the winding and the coil configuration. For example, the gap operates around the coil configuration such that the winding does not contact any of the positions in the coil configuration. This allows the coil to be attached without damaging the coil configuration.

In one embodiment, the coil component has at least one connecting element as an electrical connection of the coil component. In particular, the connecting element is arranged on the uppermost and/or lowermost of the winding. Preferably, the connecting element Prominent in the basic configuration of the coil.

In one embodiment, the connecting element is formed directly from the wires of the coil, in particular the wire tip and/or the wire tail. Thus, separate elements are not required to form the connecting elements that will be attached to the uppermost and/or lowermost of the coil. For example, the leading and trailing ends of the wire projecting from the basic configuration of the coil. In one embodiment, at least a portion of the connecting elements have a curve. This curve is particularly different from the curve of wire winding.

The leading and/or trailing ends of the wires may alternately or additionally act on the carrier elements of the coil and/or the complete coil component.

In an alternate embodiment, the coil component has more than one separate connecting element and/or carrier element mounted to the coil. In particular, individual elements can also be attached to the uppermost and/or lowermost of the winding. For example, a separate component can be attached (to the coil) by soldering.

In the embodiment, the windings (wires) of the coils are adjacent to each other. In particular, there is no gap between the windings (wires) adjacent to each other. In this way, a highly filled coil can be realized. The following embodiments are not achievable or are difficult to implement, i.e., a procedure in which a pre-formed wire is wound around the coil configuration, since in this case the winding must be separated to connect the coils.

According to another aspect of the present invention, a manufacturing process of a coil component is provided. In particular, the procedure is suitable for the manufacture of the coil components previously described.

According to the procedure, a coil configuration and a wire are provided. For example, the coil configuration of the inserted tool. The guide wire is close to the coil configuration. For this purpose, the tool has a conduit that introduces the leads and leads Circle configuration. Even better, the wires are pushed forward in the catheter. By way of example, a force is applied to the trailing end of the wire for this purpose.

The wire then advances along a bending device, thus bending, creating at least one wire wrap around the coil configuration. By way of example, the bending device has a wall through which the wire moves to obtain a curved wire corresponding to the wall surface. Specifically, the wall surface may have a curved shape. For example, the shape of the wall is such a way that the wire moving along the wall is bent into a circular shape.

In one embodiment, moving the wire along the bending device to cause the wire to rise perpendicular to the curved plane occurs immediately or after production. This means that the wire accepts a spiral form, such as a circular spiral.

For this purpose, in one embodiment of the invention, the wall of the bending device has a corresponding rise. Alternatively, or in addition, at this point, the rise can be generated by an independent riser. An independent riser is formed, for example, a nail or plate that is offset from the wire in a direction perpendicular to the plane of curvature.

In an embodiment of the procedure, the wire tip ends are wound in a coil configuration until all windings of the coil are produced. More preferably, the wire tip is pushed forward simultaneously on the coil configuration. In particular, in this case, all completed coil windings move correspondingly around the coil configuration. This means that the coil winding has a geometry that allows for rotation and is better relative to the movement of the coil configuration.

In an embodiment of the program, all the windings in the coil After the winding is formed, the leading end and/or the trailing end of the wire are formed. In this way, the leading end and/or the trailing end of the wire can serve as a connecting element for the coil and/or a connecting element for electrical contact without the need for a separate component on the coil.

Using this procedure, it is possible to more specifically implement the coil configuration without contacting the coil. Therefore, the coil configuration and/or the mechanical stress of the wire can be reduced or even completely avoided. In addition, this procedure allows the coil to be automatically attached to the coil configuration, especially to a coil configuration in the form of a closed frame.

According to another aspect of the invention, a coil component is produced using the above procedure.

This disclosure describes several aspects of the invention. All features, which are disclosed with respect to coil components and procedures, are also disclosed with respect to various other aspects, and vice versa, even if individual features are not explicitly mentioned in the context of the various aspects.

1A to 1C are diagrams showing an embodiment of a coil component at different angles of view,

Figures 2 to 5 show a further embodiment of the coil component,

Figures 6A through 6D illustrate the manufacturing procedure steps of the coil component.

In the following figures, the same reference numerals, and more preferably, refer to the same function or structural parts of the different embodiments.

FIG. 1A shows a side view of the coil component 1. 1B The figure shows a rear view of the coil component 1.

By way of example, the coil component 1 provides a defined inductivity. The coil component 1 can be used as a passive component, for example for absorbing electromagnetic interference. The coil component 1 can also be used as a throttle valve. The coil component 1 can also be used as a transformer. In this case, more specifically, it is a transmitter for signal transmission or power transformer.

The coil component 1 has a coil configuration 2. The coil configuration 2 has the shape of a frame. In particular, the coil configuration 2 has a closed loop shape. Alternatively, the coil configuration 2 may, for example, have a shape of "D" or a rectangle. In an alternate embodiment, the coil configuration does not have a frame shape or has the shape of an open frame. For example, the coil configuration is rod shaped.

For example, the coil configuration 2 has a magnetic core that can be used to adjust the inductance of the coil component 1. In particular, the coil configuration 2 has a ferrite core or a similar core. The core is preferably formed in a single piece.

The coil component 1 has two coils 4, 5 consisting of wires 6 and 7 arranged in two opposite sections 33, 34 of the coil configuration 2. Each of the coils 4, 5 has a plurality of windings 10, 11 formed by wires 6, 7 wound around respective sections 33, 34 of the coil configuration 2.

By way of example, the wire can be a copper wire. The wire can be a round wire. Alternatively, aluminum or steel wire can be used. Alternatively, the wire can be a rectangular wire, in particular a flat wire. The wires 6, 7 may be covered with paint. The wires 6, 7 may have a cross section of 0.001 mm ² (square millimeters) to 2500 mm ² . The wire can be circular in cross section as shown in Figures 1A and 1B. The wires 6, 7 may also have other geometric cross sections, such as rectangular or square cross sections.

FIG. 1C shows a top view of the winding 10, the course of the winding 10 wound around the section 33 of the coil configuration 2, wherein the corresponding section 33 of the coil configuration 2 can be seen in a sectional view. For the sake of clarity, the additional winding of the coil 4 is not shown.

The winding 10 is wound in a circular spiral in the section 33 of the coil configuration 2. Specifically, the wrap 10 is wound around an imaginary coil bobbin 19 that runs vertically through the image plane of the 1C chart. The coil axis 19 corresponds to the longitudinal axis of the coil 4. This coil 4 has the shape of a cylindrical column.

As shown in Figs. 1A to 1C, a gap is formed between the coil configuration 2 and each of the windings 10, 11. It can be seen in Figure 1C that the gaps 8, 9 can be wound around the entire section 33, 34 of the coil configuration 2. Alternatively, the gaps 8, 9 may also be formed only between the partial sections 33, 34 of the coil configuration 2 and the respective windings 10, 11 such that the windings 10, 11 form a region that can be closely attached to the coil configuration 2 . The windings 10, 11 can also be closely attached to the coil configuration 2 in such a way that they can only rotate just without damaging the coil configuration 2 and/or the wires 8, 9. In particular, the windings 10, 11 can also be mounted to the coil configuration 2 such that they can rotate without play.

The shape of each of the windings 10, 11 is not complementary to the shape of the coil configuration 2. In particular, the shape of the windings 10, 11 in the top view is different from the outer circumference 3 of the respective sections 33, 34 of the coil configuration 2. As can be seen in Figure 1C, the wrap 10 has a circular shape. The outer peripheral line 3 of the corresponding section 33 of the coil configuration 2 has a rectangular shape.

The geometry of each of the windings 10, 11 allows the windings 10, 11 to be wound around the segments 33, 34 corresponding to the coil configuration 2 for rotation. The fully formed coils 4, 5 in this case can obstruct the rotation of the windings 10, 11, for example, because of the curved wire ends 12, 13 and/or the curved wire ends 14, 15.

It can be seen in Figures 1A and 1B that the continuous winding 10 of the coil 4 or the continuous winding 11 of the coil 5 are close to each other. There is no gap between the windings 10 and 11. This gives the coils 4, 5 a high degree of filling.

The wire ends 12, 13 (Fig. 1A) and the wire ends 14, 15 (Fig. 1B) of the coils 4, 5 protrude from the basic configuration of the cylindrical columns of the coils 4, 5. In particular, the wire ends 12, 13 and the wire end ends 14, 15 each have a straight section. For example, the wire ends 12, 13 and the wire end ends 14, 15 have at least one section running parallel to the coil axes of the coils 4, 5. The wire ends 12, 13 and the wire ends 14, 15 pass through the holes of the carrier 16, enabling the coils 4, 5 to be electrically connected. This means that the wire ends 12, 13 and the wire ends 14, 15 can also serve as the connecting elements 21, 22, 23, 24. Specifically, the coil component 1 can be a pin through hole (PTH) component. In this case, the connecting elements 21, 22, 23, 24 can be inserted and fixed to the circuit board through holes in the circuit board, in particular by soldering. In an alternate embodiment, the coil component is part of a surface-mounted device (SMD). In this case, the connecting elements 21, 22, 23, 24 can be mounted and fixed on the circuit board, in particular by soldering.

In an alternate embodiment, the carrier 16 can also be discarded. Furthermore, the wire ends 12, 13 and the wire end ends 14, 15 can function as a carrier, especially as a support leg for the coil component 1.

Fig. 2 shows a side view of another embodiment of the coil component 1.

The coil component 1 is different from the coil component 1 of Fig. 1A, and there is a gap 17 between the continuous windings 10 (rings) of the coil 4. Therefore, the wires (continuously wound) 10 are not in direct contact with each other. Further, the coil 5 also has a gap 18 between two (circles) of continuous windings. This means that the pitch of the coil 4 is greater than the thickness of the wire. The coil component 1 has only two complete windings 10 per coil 4.

For example, the wires 6, 7 have a thickness of between 0.4 and 8.0 mm (millimeters); for example, a thickness of 1.8 mm. For example, the outer diameter of the coil 4 or 5 is in the range of 3 to 25 mm; for example, the outer diameter is 14 mm. The inner diameter of the coil 4 or 5 is in the range of 2 to 20 mm, in particular 9 mm. The ratio of the outer diameter of the coil 4 or 5 to the diameter of the wire 6 or 7 is in the range of 3 to 20; in particular, the ratio may be less than or equal to 10.

Fig. 3 shows a perspective view of another embodiment of the coil component 1. For example, it may be an SMD component, a surface mount device that is shaped to be mounted on a circuit board.

In Figures 1A through 1C, the coil configuration 2 and the coils 4, 5 show a basic configuration similar to the coil configuration. In the present case, the coil component 1 is arranged on the carrier 16 in such a way that the base of the toroidal coil configuration 2 is parallel to the top side of the carrier 16. Corresponding to this, the course of the coil axes of the coils 4, 5 is perpendicular to the top side of the carrier 16.

There is a separation strip 36 between the coils 4, 5 intended to increase the insulation of the coils 4, 5 from each other. For example, the separation tape 36 is attached after the coil process.

The wire ends 12, 13 and the wire end ends 14, 15 are guided from the direction perpendicular to the coil axis in the windings 10, 11 to the through holes of the carrier 16, where they are outwardly curved. For example, the wire ends 14, 15 are disassembled after the coil process is wrapped around the jig and turned into a straight line. Subsequently, the wire ends 14, 15 and the wire ends 12, 13 are passed through the through holes in the carrier 16 and bent outward.

A tilted side view of a further embodiment of the coil component 1 shown in Fig. 4A. Fig. 4B shows an oblique rear view of the coil component 1.

The coil component 1 has a slanted outer edge that approximates the coil configuration 2 of the rectangular frame. The coil configuration 2 has a ferrite core, wherein the ferrite core has a coating, in particular an electrically insulating plastic coating.

The wires 6, 7 of the coils 4, 5 are flat wires. For example, the wires 6, 7 have a rectangular cross section. The wires 6, 7 have a larger lateral surface and a smaller lateral surface that is wound around the coil configuration 2 with the coil axis being nearly perpendicular to the larger lateral surface. In particular, the wires 6, 7 are wound around the coil configuration 2 in an upright manner. The windings 10 of the coils 4 are closely adjacent, in particular without gaps. This means that the pitch of the coils 4 corresponds to the wire diameter. In electrical applications, such coils 4, 5 can have high currents in high inductance due to high turns.

Coil part 1 has connecting elements 21, 22, 23, 24 As an electrical connection. Furthermore, the connecting elements 21, 22, 23, 24 can be mounting carrier elements of the coil component 1. The connecting elements 21, 22, 23, 24 are derived from the basic configuration of the cylindrical columns of the coils 4, 5. In the manner of the coils 4, 5 in the manner of Figures 4A and 4B, the connecting elements 21, 22, 23, 24 allow the coils 4, 5 to be placed in a standing position on the carrier. In particular, the winding axis is perpendicular to the surface of the carrier on which the coil component 1 is placed.

The two connecting elements 21, 22 are formed directly by the wire ends 12, 13, and the other two connecting elements 23, 24 are attached to the wire head ends 14, 15 as separate elements. With the connecting elements 23, 24 attached to the wire head ends 14, 15, the wire head ends 14, 15 do not protrude from the basic configuration of the coils 4, 5. For example, the separate connecting elements 23, 24 are welded to the coils 4, 5. The attachment can also be carried out by other means, such as a press-fit process or a surface mounting process.

In an alternative embodiment, all of the connecting elements 21, 22, 23, 24 are formed by wire ends 12, 13 and wire end ends 14, 15. Alternatively, all of the connecting elements 21, 22, 23, 24 can still be formed as separate elements that are connected to the wire ends 12, 13 or the wire ends 14, 15, respectively.

Fig. 5 shows a perspective view of another embodiment of the coil component 1.

In contrast to the coil components of Figs. 4A and 4B, the coil component 1 is in a lying position. In particular, the coil component 1 has connecting elements 21, 22, 23, 24 which can be used to place the coil component 1 on the carrier, while the winding axes of the coils 4, 5 are parallel to the carrier surface.

Similar to the coil component 1 of Figures 4A and 4B, two companies The connectors 21, 22 are formed directly from the wire ends 12, 13, and the two separate connecting members 23, 24 can be attached to the wire ends 14, 15 such as the welds 37. Alternatively, all of the connecting element ends 21, 22, 23, 24 may be formed by wires 12, 13 and wire tip ends 14, 15, or attached to wire ends 12, 13 and wire tip ends 14, 15.

According to Figs. 6A to 6D, a manufacturing procedure of a coil component, such as the coil component according to Figs. 1 to 5, will now be described.

The present invention provides a coil configuration 2 that can be seen in the cross-sectional view of Figure 6A. The coil configuration 2 has a closed frame shape. In particular, the coil configuration 2 is a rectangular frame. Other shapes, such as a circular or D-shaped shape, are also possible. The coil configuration 2 can also have other frame shapes. For example, it can have a stick shape. The coil configuration 2 is inserted into a tool 30, particularly into the recess of the tool 30.

The wire 6 is inserted into the guide 25 of the tool 30 and advanced in the direction of the arrow. The guide 25 completely conforms to the wire 6. For example, the wire 6 can have a circular or rectangular cross section. Or it may be a flat wire, especially if it stands upright on the coil configuration 2. It can be a copper wire, and even better is an enameled wire. A slider (not shown) pushes the wire 6 forward as the wire moves forward.

The guide 25 has a straight section 26 and a curved section 27. The curved section 27 forms a bending device 28. The wire 6 is pushed forward through the straight section 26 of the coil configuration 2, for example to the outside of the coil configuration 2.

As can be seen in Figure 6B, the wire 6 enters the curved section 27 and faces the wall of the curved section 27. This causes the wire 6 to be in the coil configuration Bending in the direction of the opening 32 of 2. In particular, the wire 6 is converted into a circular shape and then introduced into the section 33 of the coil configuration 2. Thus, the bending device 28 produces a winding around the wire 6 in the coil configuration 2. Specifically, the bending device 28 is a forming device.

For example, the wire 6 is shaped by means of the guide 25 and in particular the bending means 28, without directly contacting the coil configuration 2 during the winding process. In particular, the wire 6 is separated from the coil configuration 2 during the winding process.

Alternatively, the wire 6 can be in close proximity to contact the coil configuration 2. In this case, since the winding 10 is screwed into the coil configuration 2 in the longitudinal direction, the spiral mark of the wire 6 can be developed on the coil configuration. In contrast, in the case of known methods, the winding is made around the coil configuration, without the need to wrap around the coil configuration, forming a dent in the coil configuration and/or the wire.

In an alternative embodiment, the individual's fingers are used to rotate the wire 6, rather than the continuous guide 25, thereby causing the wire to be reciprocated against the finger when it is moved, and the wire is bent into a circle by the finger.

Furthermore, instead of forming a guiding manner, the coil configuration 2 opening 32 is introduced from the front of the straight section, in which case the curved section 27 is wound towards the outside of the coil configuration 2. In this case, the wire winding is wound from the inside to the outside of the ring frame 2.

In addition to the curved wire 6 in this plane, the wire 6 also rises from the plane. For this purpose, the guide 25 can have a corresponding rise so that the function of the guide 25 acts as a riser 29 at the same time. In particular, the guide 25 can spirally run around the section of the coil configuration 2. or The riser wire 6 can also be produced by a separate riser.

The wire 6 is pushed further forward so that the wire tip end 14 is wound around the section 33 of the coil configuration 2 until the coil of wire 6 is fully produced.

Fig. 6C is a perspective view showing the manufacture of all the windings 10 of the coil component 1.

The front end of the substantially cylindrical shape of the cylindrical column of the winding 4 formed by the wire tip end 14 is formed. The wire tail 12 runs linearly and protrudes from the basic configuration of the coil 4.

At a further process step, the wire tip end 14 is bent outwardly from the basic configuration of the coil 4. At this point, the wire tip end 14 can be used as a connecting element and/or a carrier element.

Fig. 6D shows the process in which the wire tip end 14 is bent outward to form the connecting member 23.

For this purpose, the tool 30 has a forming element 31 which may be in the form of a plate or a finger. The forming element 31 leads the wire tip end 14 in a manner that contacts the wire tip end 14 and pushes the wire tip end 14 away from the outside of the winding geometry. In this case, a counter-stop can also be used to prevent the wire tip end 14 from being pressed.

The tool 30 can also have a plurality of forming elements 31 that can act in successive directions from different directions to bend the wire tip end 14 into a desired shape. Additionally or alternatively, the wire tail 12 may be formed from one or more forming elements after the winding process.

More preferably, the wire tip end 14 and/or the wire tail are formed The ends 12, the coils 4, or at least a portion thereof, should still incorporate the guides 25. In this case, a counter force can be applied through the guide member 26.

In an alternate embodiment, one or more separate connecting elements are attached to the wire tip end and/or the wire tail end by soldering.

In one embodiment of the process, an additional wire coil can be created simultaneously around another section, such as an opposing section of a coil configuration 2. For this purpose, it is necessary to be able to provide further guidance to further bend the device and further raise the device.

Using this method, the wire can automatically wind the coil configuration. In particular, it can also automatically form the wire tip and/or the wire tail. As electrons are increasingly miniaturized, as the current is increased, the coil core becomes smaller and smaller, and the diameter of the wire becomes larger. In particular, the described procedure can also be used to automatically wind a small enclosed core using thick wires, as in the example of FIG. The wire can have any cross section, especially a circular or rectangular cross section.

In order to create a coil, there is no need to wind a mandrel, especially without a co-rotating or fixed winding mandrel. In particular, the coil configuration is stationary during the winding process. Furthermore, the wire can be wound in a contactless manner around the coil configuration. This allows, for example, coil attachment directly to the ferrite core without the need for an additional housing or bandage to protect the core. In contrast to the procedure in which the wire is wound around a mandrel, the strength requirements of the coating on the wire are reduced.
